Get all the edges from a set of vertexes

I am new to Gremlin and am trying to list all the edges that connect a set of nodes:

const vertexes = g.V().where(...).toList()
[1]
[2]
[4]

I want to retrieve all the edges that connect [1],[2] and [4] excluding all the other edges.

For the moment, I wrote the following:

g.V(vertexes).bothE().dedup().toList()

But this command will return all the edges from and to the selected vertexes including edges coming and going to other not selected vertexes.

You just need to filter the edges by the adjacent vertex:

gremlin> g.V(1,2,3).bothE().dedup().where(otherV().hasId(1,2,3))
==>e[9][1-created->3]
==>e[7][1-knows->2]

You can read more about these sorts of patterns in the TinkerPop Gremlin Recipes.
